We are learning ALL sorts of interesting things about the gal who trusted Justin Bieber enough to drag race her around DRUNK this morning.

One of those interesting things is that she seems to like naughty behavior, as we’re guessing based on her foreboding handcuff necklace in the photo above. Another fun fact is that she's a self-proclaimed “eyebrow connoisseur”!

We reported on it earlier, but we got to thinking …just what does it take to be one of those?

Well! You have to own a nice pair of shapely eye bristles for starters, and then you have to know how to WERK those puppies!!

Which Chantel Jeffries DEFINITELY knows how to do, based on a fierce set of Instagram selfies.

OH, and it helps to be SO incredibly into eyebrows that you’ve even made your own eyebrow brush — which Chantel has also done! DANG!!

Check out her special brow-grooming tool along with other photos of Miz Jeffries (below)!

She might not have the safest buds around town, but she definitely has some of the sharpest brows — that's for sure!!
